Welcome to the site mate. The 1.8 coupe is a good motor, i have one myself and love it to bits! Its not the quickest car in the world but it isnt slow eitehr if you know what i mean lol mpg isnt great to be honest lol but the price at the pumps doesnt help this! The ride is quite firm but comfortable imo!
When looking at one just look for the usual accident damage, service records etc...one thing to check is if the timing belt, auxillary belt and water pump have been done at the correct intervals! Every 4 years or every 40k.
