Oh, this is easy. My grandmother's 1995 Chrysler Concorde is by an enormous margin the worst car I've ever driven. Hers is basically new, with just 8,000 miles on them. It has, quite literally, been owned by a little old lady who only ever drives it to the shops once a month. So I expected it to be tolerable, especially since the LH cars were very well received at the time.
How wrong I was. The interior, for a start, is horrific. The plastics are appallingly cheap and the fake wood trim doesn't even try to be convincing. After 20 years, even though it's been garaged all this time, the cheap plastics have aged terribly and the material haven't really held up. Also, despite being 5.1 metres long (longer than the BMW E38) the interior has very little legroom and the driving position is quite strange. In order for me, at only 178 cm, to fit properly behind the pedals, I need to raise the electric (split bench) seat up until my head is nearly touching the headliner. If I simply move the seat backwards then there's almost no room for someone to sit behind me.
The one good thing about it is that it does make a nice sound on idle, courtesy of the 3.3 litre V6. Any hope of performance is ruined as soon as you start moving, however. The steering wheel is covered in rubbery plastic so squidgy that you can feel the metal rod inside, and the steering itself offers no feel from the slow and overassisted rack. The gearbox is a tolerable 4 speed column shift automatic. It takes about a second and a half to kick down if you want any kind of acceleration, but otherwise it's fairly smooth. The brakes are odd and quite unnerving; in stark contrast to all the other controls they take a worryingly high force to yield any meaningful reduction in speed. The pedal feel is also quite strange, as if the pads have become hard and brittle. And then there's the suspension. My mum has complained of seasickenss in this car. It rolls so much in the corners that you worry about scraping the door handles on the tarmac. The body motions are appalling and there's very little control to it.
It's a turd of the highest order, basically. It feels unsafe to drive and is very poorly designed and built.
