Hi all, not yet a Suzuki owner but toying with a GV diesel in a few months! Looking to spend around £1500 ish, so the usual questions

. What to look/check for? Mazda or Peugeot engine and can these both have performance upgrades done ie, intercooler upgrade, chip/remap, de cat/ exhaust upgrade, K&N filter or similar. Thanks in advance, Watty
