Praveen Penmetsa of Long Beach, Calif., 43, co-founder and CEO of Motivo Engineering, on his 1990 BMW 325i, as told to A.J. Baime.


I was looking for a car to drive on racetracks. I have been in all kinds of exotic machinery, but I wanted to approach this car with the same philosophy I use in business: How can I do a lot with very little? How can I get the most speed, the most safety, the most fun, for the least investment?


One day in 2007, I was driving through Costa Mesa when I saw this broken-down BMW in front of someone’s home. I have a thing for white cars, and this was exactly the model I was looking for. [The car is from the second generation of BMW’s 3-series. The German company launched the seventh-generation this year.] So I knocked on the door. The guy said that the car did not run, that he did not know why, and that it had been sitting a long time. He said, “Pay cash and it’s yours.”

The car had 210,000 miles. It smelled rotten inside and was covered in cobwebs. I paid $800 and called for a tow truck.

The first thing I did was buy a new battery and replace the fuel pump and the fuel filter. Right away, the engine started. So for less than $500 of repairs, I had a working car. I pulled out all the soundproofing. I installed a custom-made roll-cage. I bought a used racing suit, a used helmet and borrowed some better wheels from a friend.

It took four years before I was able to take the car to its first track day, at Buttonwillow, two hours north of Los Angeles. By the end of the day, I realized that the smartest way to find more speed in the car was to focus not on the car at all, but rather on me. So I started picking up skills and improving.


Over the years I have worked on this car always with the philosophy of doing the most I can with the least investment. I have taken it to tracks all over California. It is street legal, so I don’t have to trailer it. It is so loud that I wear earplugs when I’m driving, and when I get to a track, I swap on racing tires and I am ready to go.

People love to see this car that has over 240,000 miles hunting down new Porsches. For an $800 initial investment, I have gotten my money’s worth.

nice story , but i wonder what he did on suspension and brakes…...to make it a "race" car .
Some years ago a "cheap" BMW 325i was also a much used "track" car over here, but for serious fun you need to change a few things…… so a $1k car becomes quick a $10k one.

Last I checked a good 5pt harness is $250 and an HNR is $500. Amazing that he got the rest done for only $50.

$800 was the original purchase price. Says he spent $500 just to get it running. Who knows how much he has into it. (Do any of us want to know??)

I’d say the average investment into a Lemons car is around $5-$10k, assuming $80/hr for donated labor. But building a front running Lemons or track day car is very different than building a car that can podium with SVRA or SCCA. Think 4x more if starting from a decrepit street car.
