Hi,
Insurance is a difficult question to answer as everybody has different circumstances, age, no claims, motoring convictions, where you live, where the car is kept and how you use it, commuting, social etc etc.
All these factors make it very difficult to compare, however I got insurance through MG themselves (I am 65, live in Dumfries and only have 5 years no claims (lived overseas for many years and only came back to the UK 5 years ago) and I am paying them just under £400.
Look on the MG webpage, go into the Owners tab and you will find the links to get a quote.
Regards
Frank
