Clearly, PNP is taking a cue from the classic National Lampoon cover here, and what vehicle could be cuter than a chrome-bumper MGB-GT? It's like a friendly little puppy, begging you to save it from death! A friendly puppy that spends most of its time at the vet and leaks all over the house, that is, but just look at it!
Whoever is writing Pick-N-Pull's Craigslist ads has a good sense of humor. We see the two possible outcomes to the "you don't buy the car" scenario. One shows the parking spot- complete with oil stain- in which the MG once sat prior to its new owner hauling it away; the other shows The Crusher working up a good appetite with a Volvo wagon entree, with the heavy implication being that the MG will be dessert. Lines like "Buy this car and you will know what you will be doing for many months to come" and "Legendary Lucas Reliability" imply that the writer has at least a passing acquaintance with British Leyland products. Here's a giant screen shot of the original ad, just in case someone snaps up that super-bargain and the ad gets pulled. Thanks to Casadelshawn for the tip!
