The Volkswagen Jetta is VW's more affordable sedan. There are five trim levels available: base, S, SE, SEL and TDI. The base car is a stripper that doesn't even come with air-conditioning. As such, you'll likely want the S, which includes power/heated side mirrors, power door locks, air-conditioning and keyless entry. Both of these lower trims are powered by a 2.0-liter four-cylinder that produces a wheezy 115 horsepower. Stepping up to the SE and SEL trims gets you a more desirable 2.5-liter five-cylinder good for 170 hp.
