Until my Land Rover was recommissioned, my 1972 4/4 was a daily driver for three years. It was last rebuilt in 1996 and was used as a high days and holidays car until June 2008 when the Land Rover came off the road. For the next few years, to July 2011, when the Land Rover was finished, the Morgan was used for everything, Tescos, commuting, trips to clients, parts barge for the Land Rover, the lot! Before you think the Morgan was babied, it did between 15-20k miles a year for the three years.
My Morgan is now in a sorry state, but it has done over 100,000 miles since the last rebuild, (and Kent engines get a bit breathy). and will be put back on the road sometime.
The brakes were the least of my worries - the lousy quality of reproduction points was the biggest problem. Electronic ignition might be a good idea, but I can fault find points with a circuit tester, file and feeler gauges.
A modern Morgan will be fine, but the mileage may monster the value, if you want to sell it after 2-3 years.
