He's confused, Scotty. He thinks you mean the Roadster Enduro, I believe.
There are a number of cars that will work well. The Ruf 3400S is a good candidate. At any rate, look around a little here. Try searching, and try the Writeups board.
the I assume you mean the Spoon S2000, because the Civic doesn't qualify as a roadster. If you're fast, go with the 3400S. And check out the Online Racing forum - try the Weekly Challenge!
The speedster is a good car to use too... Personally i think this cup is one of hte easiest prof races... and you really shouldnt have a prob with most moderately modded cars... The 3400s is a good car, really fast for the series. The spoon s2000/mugen s2000/ s2000 are all going to be fast enough and slightly easier to drive if you are driving with tcs and asm ( which i would not recommend). Still slower but light cars like the speedster should make hte race more enjoyable... I really like the speedster and use it any chance i get
The 3400S should do it really easily for you, if you have trouble...you really need to practice more, or maybe put something in there (Turbo stage 2) to help you along...I haven't done this series in yonks though.
Spider & Roadster is really too easy to bother getting a car just for that event. You might as well use something you've already upgraded. Good options are:
Use a RUF 3400S that you used for the Boxer Spirit
Use an SLK 230 Kompressor that you used for the Silver Arrow
Use an Elise 190 that you used for the Elise Trophy
