I've heard the AC is a bit weak in these cars, but you should be feeling war air. Get your AC recharged or take it in to get looked at. I can't imagine driving in 105 heat without it!
I figure it's better to have it than to not have it. They're not that expensive that you'd be wasting a ton of money. But if you're driving 100 mph, don't think your radar detector is going to be your ticket to freedom.
You sold it for a trucks??? You're nuts! Haha. Searching for the right car is like a needle in a haystack. I'm always compromising just so I can hop in and start driving finally. Haha.
I'd be weary about buying an earlier version of the RX-8, especially one with 110k miles on the clock. These cars are great, but just get it checked out before you lay down 9 grand.
