Description for BMW 3-Series 1991

Up for sale is my Brilliantrot 1991 325i with 1995 M3 engine and transmission. The car has been very heavily modified with the aim of creating an incredible driver’s car which turns heads and can be taken grocery shopping.

The car was built in March of 1991, making it a last year and last month model. The car was sold in Virginia that July. The vehicle was taken off the road sometime between 2005 and 2006, and was not re-registered until 2013. It spent a just under a year in Minnesota before being brought to New York where it has remained since.

I purchased the vehicle in January of 2017 and in May of 2017 swapped in an engine and transmission from a 183K mile 1995 M3. The engine had been serviced thoroughly by it’s previous owner including welding of the oil pump nut. The engine was tuned by RK tuning on long island before I purchased it.

In May of 2018 the vehicle was hit on the right front corner, which pushed the right front wheel into the passenger’s footwell and totaled the car. Luckily the subframe, shock tower, and all other mounting points remained intact. The car was professionally repaired by replacing both front fenders, valence, bumper, and completely respraying the car. At this time all the rust was repaired except for a small hole under the battery.

As I am moving to California I would rather sell this than go through the expense of making it SMOG legal.
