2014 Defender 110 - specialist garages in North Hampshire/ Basingstoke area or nearish?
Looking for a local business who can do a number of jobs on my Defender - dont what to go to the likes of Harwoods and other main dealerships.
Wiring of retro fit add ons and some other bespoke jobs.
Any suggestions much appreciated.

A friend uses ASV near Andover… https://www.asvrepairs.co.uk/

Google shows numerous specialists in the Hampshire area otherwise. Could be worth trying one of the local Land Rover clubs for a recommendation.
