Hi there!
Ah, new cars... I very much second the recommendation to check out Consumer Reports! They are at
www.consumerreports.org, and if you pay $24 for a year, you can look at all their stuff online. Their Annual Reviews book could be at libraries too, as mentioned... if not, their store online sells car-buying guides and a "new car buying kit."
They are awesome (yes I'm fawning!) because they are 100% neutral in their publishing... they buy the cars anonymously, and then go over them like crazed car nuts looking for any flaws, and rate their performance.
They have been right on about the 3 cars I've owned, and the reliability records they provide from surveying their thousands of readers are worth their weight in gold.
Are you looking for used? new? Sedan? Minivan? 4-wheel drive something? They got it all
On Jeeps - go for the Liberty, not the Grand Cherokee. No offense to your Grand Cherokee owners out there, but they break down quite a bit, and the ride, emergency handling, brakes all are poor.
Personally, I'd go for a Honda anything. They're great. Toyotas are also excellent...
Happy car shopping!
