MGB's are fun and easy to maintain.All this guff about the electrical system can be reduced to voltage regulators,light switches and engine/chassis ground strap integrity,mind you,this only holds true when these cars are used occasionally and stored most of the year as all cars suffer from static desuetude,in other words,they suffer from lack of use.Something that seems endemic to British sportscars.Bear in mind the MGB's were production cars and suffered on that account
I've had several.They were,once certain aforementioned problems were addressed,very reliable,fun,primitive and bone-shaking.
My personal favorites are the M.G.TC,TF and MGA of which there are always a very representative sampling offered for sale.
If your wallet permits,a nice vintage Riley 9 or Morgan will offer you a helluva lot more fun,value and reliability,even an HRG.
