Need to know which model, year, mileage and which level of service it is to even begin to guess that one please.
L reg, 7500 miles? Maybe you mean 75000. Sorry still not possible to say. A honda garage would not be able to quote without knowing more about it and what services were done last. when was the cambelt last changed for example. when was the coolant and brake fluid last renewed.
Suggest you go with the car and the service record to a Honda dealer and get a quote. if you do not have the service ecord then the only answer would be to get everything done which could cost about £650 I would estimate
