Really interesting topic!
In terms of new car buying;
- Major drivetrain problems, for example many reports of transmissions or clutches being replaced due to failed parts and/or poor shifting actions. However it is difficult from reading Forums to determine the extent of these problems and whether they have been solved in currently produced cars. Similar to these, too heavy a clutch, too notchy shifting, won't go into gear, missed shifts, clunking etc. are deal breakers. How well a manual transmission works is a priority for me.
- Inadequate torque and power. I know I will get tired of shortfalls in these areas very quickly, then waste $ thousands to get out of the car and into something else.
- Too heavy for the size of the car. Weight makes everything worse, except sometimes quietness.
- A CVT is absolutely a deal breaker. Most automatics are deal breakers.
- Convertibles are deal breakers, because its too much sun, cold, heat, wind, and rattles and excess weight etc.
- No dealer within a reasonable distance of home and located in heavy traffic areas. Too much aggravation getting service.
