Seeking advice, from the Car Enthusiasts

You don't say how old the Jetta is in comparison to your existing car, nor how many miles both have driven.

In terms of quality VW have a rep for quality and Vauxhall do not, BUT the insignia is one of Vauxhalls slightly more premium cars whereas the Jetta is a base level vehicle, and of course a salesman isn't offering you the swap for YOUR benefit.

Automatic gearboxes are great.

They free up your left arm and foot. makes eating, drinking, rolling a bifta, some forms of sex, answering the phone or changing the CD much easier (and safer!) to accomplish whilst on the move.. 

Cars are designed to last between ten and twenty years now (or between 100 and 200 thousand miles) and everything is designed to fail at once (excepting consumables) at that point, so age and mileage are way more important that looks or provenance.

When we sell our VW Lupo sport, it'll be super clean, have a recent change of thick oil, and the true description "One Lady Owner".

In practice the poor sod who buys this will be buying a vehicle that has possibly never been beaten off the lights when I've tried, and VERY rarely been passed. A vehicle in which I did over 130 MPH in Germany, and regularly used to annhilate boy racers with. It drives nice because we had to replace pretty much all the suspension bushes, and shocks etc, a couple of years back because roadholding is IMPORTANT when you drive fast. (and occasionally in the past very competitively indeed. E.G. My MRs after some goit has just trapped me from leaving the slow lane despite me indicating by accelerating into the space I needed : "'Sperg, it's an Audi a6, you can't beat that", followed by my reply, "yes it is, but none keeps to 120 for very long any more..." And I was right!     

My point being our car looks like it has been well maintained and looked after, (and it has been largely to a much better standard than often is the case) it's a super desirable model, so we would get decent money for it still, but no-one would expect me to disclose the supplementary information, which I just revealed...   

If the car you have does what you want, and it isn't at the "end of life" part of the "reliability bathtub curve" I'd think very carefully before parting with it.

If any car you are looking at has a lemon scented air freshener in it, particularly in an auction, unless you are very knowledgeable indeed you should definitely walk away.

There's over 100k miles on my Insignia. So, I drive too much.

I remember a Garfield and Friends episode about Al J Swindler, who caught Jon out with his car.
