Just to add my 2p ,
I have driven a 1.4 Corsa B on a few occasions over a 9 month period helping my mate restore his mini, and even helped him service it,
My first impression of the car from opening the door was not too bad, basic as you would expect, plastics and fittings arent the best but its no luxobarge- so you expect it. The seats are fairly comfortable at first, but are a bit like an old sofa, after a while the lack of support makes them uncomfortable.
The pedals are in a slightly soppy position, as stated above you tend to catch the dash with your feet, steering wheel adjustment is limited - but acceptable. I can't call the driving position good , but its not terrible , as with the interior , just budget.
What totally kills this car is the frankly shocking driving experience, the steering is very wooly and doesnt inspire any confidence that the car will actually go where you want. The clutch is so light and unresponsive that you honestly wonder if it is connected, as the biting point is variable and hard to find with no clutch feedback (maybe not best for a new driver ?),
the brakes are the same - they work but dont really feel as if they are going to until the last minute when the car stops ( this is after replaced pads and fluid, and a master cyl test , so no , it wasnt broken, even checked the flexi-lines).
The throttle is ok however, works as expected really, and to my surprise the 1.4 is not toooo slow.
Unfortunatly, the gearshift is honestly scary, you cant even tell if the thing is in gear. Now i thought this was down to bushes, but after talking to a few owners it seems its common for the shifter to feel disconnected and wobbly.
I wont go on about the handling because its not supposed to be a sports car, all i will say is on budget tyres its a total death trap , so be careful.
On the upside its a simple joy to work on, as its so basic.
Overall, in my opinion of course, it would be an acceptable car for a budget if it didn't feel so darn wooly and dangerous to drive.
Ask if you want me to expand.
