Welcome from Wales.
I have a 2002 Plus8 and no issues. Good choice of car you have made.
"Check engine " light has come on a couple of times but reset with a Maxiscan.
Random intermittent misfire was the fault code. Undetectable whilst driving. Engine was running nicely. I have been using Shell VPower petrol and the light stays off. Itame on earlier this year when normal 95 octane was used on a weekender. VPower won't break the bank for my 7k+ annual mileage.
My advice.....use the car!
Regular oil changes and lubricate the suspension often ( front and back).
Post some photos here too!
