Absolutely not! I have tracked and driven the R hard. sold with 14K plus miles and still trucking.
R tracked at, Daytona, Sebring, Barber, NCM, Lil Tally and Road Atlanta. The car is a monster!
Track time undoubtedly is more frequent and cheaper in our Champ car. Not to mention the competitive door to door driving aspect of an endurance race. To be honest, The R was boring in that regard. Nothing ever really went wrong. other than routine maintenance, that was it. Also, driving fast in the R is easy, not so in the Saturn lol. Keeping our Saturn running for 20hrs or so, that! is a challenge and extremely satisfying.
