CAR DECISION HELP!!! bmw,lexus,infinti,hyundai?

Based on price and performance I'd probably have to go with the Hyundai since it's about $10,000 less then all 3 of the others. All 4 will have good resale value, which is typical of sports coupe's. The Genesis doesn't come in a convertible though, so I guess that will take it off your list. For pure performance the BMW is probably best, but also expensive and the smallest. So, I'd go with the 330 HP Infiniti G37 with it's normally aspirated engine, put a $5000 supercharger on it and you've got more HP then an IS-F!!
