I really wanted to hate this car - got it cause I needed long distance car that can cruise at 80 mph without getting a bottom ache, and will return quite good mpg.
It's hard to fault the car - the above niggles are annoying, but forget about them and the car cruises at 80mph on the motorways with ease, nice and smooth and not demanding to drive and not hard work like other cars.
Handles wonderfully. It is quite soft suspension with a bit of body lean, yet it's almost quite chuckable. When things lose grip, it does very predictable understeer, which is easy to correct, so thumbs up in the handling department.
No rust as you'd expect from galvanised bodywork.
Brakes are a bit annoying, I hate rear drums, on every car I've had with drum brakes, they've all squeaked.
Interior is rather spacious feeling. All controls work, electric windows a bit slow, but come on, this is a 15 year old car, as long as it opens! Wish it had the seats from the older 405 (1992 and earlier) as they were flatter and much more 'sofa' like. newer ones are a bit bucket like and not quite so comfy...can't understand why you'd put bucket seats in a diesel?!?!
Also, there's a spoiler on the car... quite a big one too - my car is the saloon and it is the standard one, but why fit it on a car that won't do much more than 100mph total... so very weird.
Think I'm getting quite good mpg at the moment, not as good as I hoped, but well, it's better than most cars at high speeds...
Must add (slightly off topic) on my old 405 I drove to Newquay in it (300 miles each way) and we drove at night and did the whole journey in one hit, didn't stop once. Got out the other end and my bum wasn't numb! Amazing!
This is my second 405, and I'd get another one... and another one (if a good example turned up!)
