I can tell by looking at the pictures under the hood what engine it is. The differences are striking. I believe the turbo diesel is accurate since I am looking at 98-99 models where it is turbo. I suspect that these cars have had paint jobs. I thought maybe these cars had logos that fell off accidently. I just found it odd that 3 different cars all by reputable, established ebay dealers would have different variations on e300 on the trunk like. The orange peel finish is a good tip. Thanks!
