If your a speed freak and want the Bimmer as a toy then try to look for a grey unit E36 325i. We used to have one before and I can honestly say that it was one of the best A/T car i have driven, the 325i has 190hp with torque to boot. you can use it to challenge Civic Sir, Lynx RS. Repairs and maintainance is more expensive than your regular jap sedan but its not that high unless a major problem has arisen. since its gonna be a toy car, i doubt it would get more than 10Tkm a year, so servicing would be cheaper since its not an everyday car.
If you plan to get a second hand unit, just be sure to check the car thoroughly since major repairs would equal bigger costs.

You could also get the E30 model 320i or 325i but if you had the money i would rather get the E30 M3. Probably one of the ultimate toy cars around.
