I ended up getting a fully equiped 2006 Smart Fortwo CDI.
0.8L turbo diesel
6 speed manual with electronic clutch.
3.3l/100km(71 MPG US)
I wasn't even considering it because I thought the engine would scream along at high rpm on the highway. I thought the short wheel base would make it unstable and blown around by larger vehicles. I test drove one; 2000rpm at 100km/h(miata does 3300rpm). Its stable and comfortable at highway speeds. I found the car for sale from a guy that was moving across the country and had 2 days to sell the car so I got an excellent price. Hopefully it will be reliable.
