This is one of my favorite sleeper sedans of the last 20 years: a 1995 Acura Integra GS-R, listed here on craigslist in Pennsylvania for $2,900. Wearing the same bodywork as the standard Integra sedan, the GS-R featured one very distinctive difference: the B18C1 DOHC VTEC motor driving the front wheels through one of the best manual gearboxes ever made. Unfortunately, a lot of these cars end up either as victims of theft or tasteless customization. This example is for sale after the owner moved to a crowded urban location, so the car is up for grabs with an upgraded intake and wires the only deviations from stock. A sleeper that gets 30 m.p.g.’s – that’s tough to beat!
