I only had this car for about 6 weeks as a hire car until my company fiesta arrives (now driving a Honda Civic).
Although I can't give anything detailed about the car I thought I would at least share my thoughts.
The looks of the car on the outside are quite plain, but the front end isn't too bad, inside its very bland and basic (I had the mid range model), things seemed very cheap and tacky including the silly location of the steering wheel controls for the CD Player.
The car at speed (over 70) is quite scary and actually starts to wobble slightly, in doesn't hold the road to well also.
Unfortuantely it was a petrol Automatic with just under 20,000 on the clock (I added about 2,500) and it absolutely guzzles petrol, 350miles for the light to come on compared to my 550miles Xantia.
That's too bad that you got yourself a Corolla with some computer problems, because every other Corolla I've ridden in is quite good. You also stated the car has a 1.6 liter engine... since when. I have never seen a late model Corolla with anything other than a 1.8 liter, and they run very strong. My '05 Corolla with an automatic has gotten as high as 43 miles per gallon with the A/C on, and averages 31 around town. I do have a question, what is a Citroen? Is that a bicycle or one of those 3-wheeled motorcycles with two wheels in the front and one in the rear with a two-stroke 125cc engine that so many UK people drive? Just curious.
A Citroen is a french car.
I think the poster may also be referring to a Robin Reliant, although the wheel configuration is reversed (one up front, two in back).
