THE race is on to get your cars ready for the second Monster Motor Show Off.

Tania Halford has spent the better part of a year working on an Alfa Romeo GTV6 for the show.

She said the project had become a labour of love.

"We are nearly there and only have a little bit left to go," Ms Halford said.

"And I'm still looking for a few challengers to enter their cars."

Organiser Mick Spiller said the Stanthorpe Historic Vehicle and Machinery Group were looking forward to the September 21 event.

"The support of the local community and visitors from far and wide last year was overwhelming," Mr Spiller said.

"With that huge support we raised $4000 for the Prostate Cancer Foundation of Australia.

"Once again all profits will go to this great cause."

Mr Spiller said this year's event promised to be even better.

"There will be something of interest for the whole family, including a display of vintage, classic and modern cars, motorcycles, trucks and tractors, stationary engines and blacksmithing," he said.

A Quilt Show also will be on at the Stanthorpe Showgrounds on September 21 and will run in conjunction with the motor show.

The Quilt Show will feature a mobile patchwork show and various craft stalls.

All funds raised will also go to prostate cancer research.

The Monster Motor Show Off starts at 9am at the Stanthorpe Showgrounds. Entry is a gold coin donation.
