Alot of these cars are not designed to last, they are designed to make the first maybe the second owner happy for the first 6 - 8 years, till they are two old for the main dealer's to care about anymore.
Then you get rid at the end of your PCP deal and buy another equally bland run of the mill car for another 3-4 years.
They get you in the door and buying these new or nearly new cars by making them look as flashy as possible on the outside but as cheap to make on the inside, hence why they don't last.
As for vauxhall, Throughout the 2000s I drove literally hundreds of them and they where all equally boring and bland, even supposedly hot VXR models, same car just more power under the bonnet.
The newer cars don't seem to have shown any improvement. Probably why GM wanted rid of them so much and why they needed buying out by Peugeot.
A very good friend of mine has a fully loaded not very old Moka, he got very cheaply from his father in law, not a car he would of otherwise bought, but how he describes it, is that he cares so little about it, that it could catch fire tomorrow and he wouldn't care one bit. Which he said was refreshing compared to previous cars he owned which were worthing caring about including an S1 Elise a couple of classic (late 90s early 2000) minis, mercedes, the list goes on. He does still keep a Mini 500 (one of the last 500 original minis made before the BMW ones appeared) but he just doesn't care about the Vauxhall.
In 5 years time fiat may be reduced to a specialist car making only electric 500s, who knows what might come out of the merger in the coming years. I like the 500x but I would only buy one if they made an abarth version. The Tipo is basically a vauxhall Hashtra. So It would be worth just waiting and seeing what you like in 5 years. There will almost certainly be a lot of new electric cars by then.
