It's hard not to have a blast in a six-speed, rear-wheel-drive convertible, which is exactly what the MX-5 offers. Don't listen to the no-headers-on-their-cars-so-they-sound-really-loud bros that tell you the Miata is a girls car. They've clearly never driven one and don't know shit about cars. If you're still looking for a little more power, you could go with the '04 MazdaSpeed, the first turbo Miata. That will definitely put you over the $10K budget, but maybe by following these tips to talk down the car dealer, you can work out a deal.
