My First Car, 1988 BMW 735i — This 7 Series Had No Redeeming Qualities. I Wanted It Anyway

Cover 1200a 1

In fall 2008, just as I was starting high school, my father stumbled across what would become my first car: a 1988 BMW 75ia, which he had never heard of. After a little googling, he figured out that it was actually a 735i, and an automatic. It was listed for $1,500, and it needed a lot of work. “Perfect” for a 14 year-old who would not start driving for six more months.

No part of the 735i was in good order when we looked at it. The engine was running on five cylinders; it felt like the shocks were worn out, the fuel gauge and instrument cluster were in semi-functional condition, and the onboard trip computer was not working. The seats were worn out, the headliner was sagging, and frankly, the car had no redeeming qualities. However, I liked it. I cannot tell you why I did, but I did. My father paid the man, and he delivered the car to the Smiths’ parking lot in Los Alamos. We picked it up later that day, and not long after (maybe even that day), we set about making the 735i work again.

The 735i cleaned up easily enough, with the biggest problems being caused by deferred maintenance. New spark plugs brought back the dead cylinder, and new rubber intake boots made it run about as smoothly as it ever could. Airing up the tires made the ride smooth out, such that it was at least a functional car. However, the electrical gremlins were far harder to deal with. A new cluster fixed the fuel gauge but took away the gear and transmission mode indicator. Weeks of trial and error brought some systems online intermittently, but these systems never worked completely correctly.

The biggest problem, however, was the transmission. The 735i was equipped with the 4HP22 automatic transmission. It was in a number of rear-wheel drive European sedans, and it was known for a particular quirk; if the engine was revved in park or neutral, and the transmission seals were just old enough, it would engage both clutch pack A (the drive gears) and clutch pack B (reverse) at the same time, destroying clutch pack A. The first time my brother drove the 735i, he nearly immediately killed the transmission–probably the only part of the car that worked well. This would also be the last time my dad ever let him drive any of his cars. After a few months, my father and I (mostly him) rebuilt the transmission and the 735i returned to the road, just in time for the Thanksgiving vacation.

While the front bumper was still off due to some repairs we were doing, my brother felt like it was a good time to “borrow” it. I came back to find it had acquired 70 miles on the odometer, and there were some branches sticking out of the auxiliary fan. Thereafter, we fixed the On Board Computer, as one of the built-in functions of the OBC was an electronic lock that would prevent the car from starting without the correct code being entered. My brother would not be able to take it again.

Viable transportation, if it’s the only thing you can find the keys to.

In June of 2009, my entire life began to fall into place. I had been signed up for a summer driving class. There, I met my first girlfriend, L. She had just moved from Texas, and did not know that I was a pariah just yet. We hit it off, and for about a month we dated. That’s when I learned that, having been a pariah since the fourth grade, I liked my solitude. L, however, liked to talk. After we broke up, I would stay single for a very long time, this time by choice. Almost as importantly, with driver’s ed came a learner’s permit. I was finally able to drive the 735i, albeit with supervision. The 735i became the biggest part of my life, and I finally became familiar with it and its eccentricities.

The 735i was equipped with the BMW M30B35 inline six, a single overhead cam engine that first appeared in 1968. The B35 was the final variant of the M30, making 208 horsepower and 215 ib-ft of torque. The M30 was old when it was new. The valve clearances required manual adjustment, and if this were ignored for too long, the engine would develop a distinct valve clatter that would never quite go away. The engine was smooth and fairly powerful, although it struggled against the 3800+ pounds of the E32 chassis. It was not terribly fuel efficient, managing about 18 mpg, although I never drove it carefully. Had I driven it with caution, it might have gotten as high as 19 mpg.

Performance-wise, it was on the slow side around town. 60 came in about 10 to 11 seconds. However, on the highway, it would charge past 100 with ease. The chassis was built for it, too. While a bit softly sprung, it handled similarly to the E30. The steering, a recirculating ball system, was made a little more sporty by way of Servotronic steering, a neat little system that reduced power steering assist as speed increased.

The 735i was mine for about four years. In 2012, my father retired and I was accepted into New Mexico State University. While the 735i was in the best shape it had been during our ownership, it was then 22 years old, still suffering from electrical gremlins, and it was not clear how much longer it could last. As I would be moving 320+ miles down to Las Cruces, where it was quite hot, my father did not want me in the 735i anymore. He found a much newer car in much better condition at an incredible price, and I was given the choice between it and his old 1998 BMW 540i 6MT. While I know I made the wrong choice in the end, I don’t think I’d make the right choice if given the opportunity to do it again.
