CESS

I've been exploring my options for a "new" car. I'm trying to find something reasonablely fun, fairly affordable to purchase and run and reliable enough to be my main car.

The A4 is seeming like a good choice - I've always wanted a convertible - But I have some questions/concerns

- I live in Alberta so put up with cold icy winters. Is there enough insulation in the top to keep me warm at -40?

- As unfortunately the top will likely be up more than down any problems with excessive cabin noise? Blind spots?

I'll likely be buying one 5-10 years old and with 100,00km or so. Any specific years to avoid? How high can I push the KM before loosing too much reliability. I know that a lot of that will have to do with how it was treated but if treated well how long do they last?

What engine / tranny choices would be the least likely to give me trouble?

Are brighter head lights, Remote start, Heated seats/stearing wheel, options?

Are Audis hard to work on? If I'm decently handy could I do basic maintenance and simple repairs myself?

Anything else I should know?

Thanks much for the time. Sorry for all the questions.
