Engine size?!
 

Why no engine size? I would like to see the "gas, lpg, diesel, v6" options also show model. Or a separate property to manually enter capacity to compare. Rounded up for those of use that write 1398 for a 1400 etc.

Take a look at this FAQ: Why don't you track more vehicle details? You might also search this forum for "engine size" and you should find several conversations on this topic.
