"Looks great, service was amazing"

I needed a new 12 pin trailer plug and some Anderson plugs fitted to my Y62. Super neat and very fast service, they also did a nice tidy up of some existing wiring in the engine bay too. Looks great, service was amazing, definitely telling everyone I speak to who has done the job.

"Takes customer service to a whole new level"

Linda takes customer service to whole new level! I wasted half a day driving store to store to replace a 40amp fuse, after each store/dealership sending me on a goose chase to one another.

"worked a treat on our recent trip"

Purchased this battery and charger from JTS.
Excellent job done of installing it for us. Everything neat and tidy. Would highly recommend JTS. Staff friendly and helpful.
This worked a treat on our recent trip to Adelaide. Kept our beer cold and the meat tray we won on the way!!
