First spotted!
Discussion
I also did my 1st spotted since I've had a Monaro.
Spotted a Red Monaro going north stuck in the traffic like me on the M1 around Luton on Saturday 6/1/08 plate starting with S555. I pulled in behind you, my wife commented on how common my is
I was in a silver Monaro taking it to Motobodies.
Should hopefully pick it up today, it has the following probs.
1) Horn didn't work, kept blowing the fuse
2) Water leaking in under the rear passenger footwell
3) Speedo sometimes going mad (displaying 200mph when the digital displays 40mph)
4) MPH light too bright (ok not a major problem but there's a legit fix for it)
I was very nice to them giving them the instructions from the LTO site on how to fix 3,4
