We use our Jeep Grand Cherokee to tow our race car around...4.7ltr V8 loads of grunt, full leather, woodgrain, power bloody everything, heated seats etc. They are rated to tow 3 ton and the best thing about them is you can pick up a decent 2000-2002 model for less than $20 000.
Only bad thing is the fuel economy.
EDIT: here's a good one for only $16 000
