I personally would go for an e-36, they are sporty, sexy and not too expensive and with some $ can be fast as f**k and hug corners like its on rails. I bought my M3 for $13K and put about $15K into it over the past 3 years. Approx. 460-480 RWHP, Just make sure you get an upgraded driveshaft if you work the motor and PUT THE HEAT SHIELD BACK ON when you replace the driveshaft.
