Been sort of going through the same question....as diesel starts to climb in cost I am beginning to lean towards gas as the best option (unless you plan to grow your own canola) ...
here's my general, and rambling, thought process to date fwiw:
For a mixed city/highway commuter
- Only reasonably priced diesel seems to be VW ... ( the Smart is not a serious highway commuter)
- ALL VW dealers (locally at least) have the same "attitude" like they are doing you a favour selling you a car
- VW's are solid and seem to handle fine - I enjoy the ride...BUT electric problems seem very common however and repair/maintenance/parts are pricey based on several friends experience who drive them - plus all but one reports "serious" attitude over warranty work/claims and general repairs..
- Diesel mtce is infrequent BUT can be very pricey ... again based on friends operating Passat diesels.
- VW Diesels seem to go on to achieve high mileage
- Honda Civics and Toyota Corolla's also achieve high mileage despite being driven hard and generally abused.
- Civics and Corolla's are extremely reliable and start readily in very cold weather - important where I am.
- Civics and Corolla's are cheap to maintain
- I am beginning to believe that annual operating costs (fuel, insurance, mtce etc etc ) make the Civic/Corolla a much cheaper proposition over 300k miles.
- Resale on Civics and Corollas is very good.
- Resale on VW seems to be all over the map.Although Diesels seem to command high prices.
