I also think its a 280se....I think that is the only thing keeping me watching the show....it is very strange.....and I can't understand why it is set in modern times when psycho was filmed in 1960 and this is suppose to be prior to the movie psycho....but yet they are driving vintage cars.....I like being human better...
Here's some photos
