welcome to the mlr. you will find plenty of information on here to help find the car for you.
personally, i stayed clear of most things advertised on eBay / auto trader / piston heads. an i found my car on here. you can generally search about what the seller has asked about also with regards to any issues they may have had, which is also a nice thing to have at the end of the fingertips.
good luck finding the motor
cheers
