Should you only use high octane gas in your sports car?

Dear Tom and Ray:

I am considering buying a Lotus Super Seven. I understand this is a high performance car that requires 93.5 octane gas. Unfortunately, I live in a very high elevation, where the highest octane gas available is 90. I would greatly appreciate your advice.

TOM: When I started reading your letter, I thought that you must have just turned 40. But by the time I finished, I was convinced it must be 50. If you had just hit 40, you'd probably go for something like a Mazda Miata or a Nissan 300 ZX. You're going for a "last chance" vehicle...and that smacks of the big 5-0.

RAY: If that's the case, why pussy-foot around? Go all the way! For $145,000 you can go to the convenience store in a brand new Lambourghini Countach. High octane gas? No problem. If you're spending that kind of money, buy yourself a Sunoco station too.
