Nothing goes wrong as long as it is full of gas (PETROL). It is a big consumer.
This car is very good, prestigious, comfortable and speedy. It is good for individual use not commercial. It is very expensive to maintain.
Toyota MarkII is not expensive to mantain, especially with fuel. A 2.5 6-cylinder supercharged twin-turbo toyota markII of 1989 - 1996 (from JZX81 to JZX90) uses about 12 lts / 100km in town, and about 10 lts /100 km on the highway. The no -turbo or non-supercharged omdels are a little less. The DOHC (Twin-Cam) 24 models are about the same as the non-DOHC. I'd say the only problem I have seen with these cars, especially those imported to Africa is that engine oil gets depleted very fast, as in 1000km!! This I have seen with many of them, and I don't know why. Else, it's a good, fas, confortable and silent car. A good replacement for E-Class Merc or 5-Series Beemer!!
I have Toyota Mark II 1995 model and so far so good haven't experienced any major problems. Its fast and comfortable. my only problem is since I bought it 2nd hand I don't have a repair manual. Does anybody no where I can get one in English? Also can anyone explain to me what is the difference between "Regalia" and "Grande". What would be a good rate of fuel consumption for this car, haven't measured it accurately, but I am doing about 7-8 litres per kilometre. I really need the ownership/repair manual.
