For $12k you are mostly limited with 07-08 e92. In terms of mileage you won't have much choice, you won't get low mileage cars at that price, so focus on getting best from what you can, be reasonable - imho it would make no difference 112k vs 125k miles car at this point and price. Just try to avoid 200k miles. What's much more important try finding car (and owner) that has maintenance records (yes they can be forged too, but rarely someone bothers with that and you can tell if owner has all records in his book and has no problem showing it to you and answering all questions or has vague recollection of what was done when).
Rust will be not an issue, as will suspension - it's usually very strong and you can feel it during test drive. Engine and transmission are usually not an issue too. What is weak point is all that things around engine that tend to fail. Ask owner for following records or history of maintenance:
1. water pump with thermostat (check if it was replaced, usually it fails at around 60-100k, so it's good to know if yours was recently replaced, otherwise it may fail any moment and you'll be paying around $400 for parts and $400-500 labor)
2. Gasket seals - there are 3 of them: valve cover gasket, oil filter housing gasket and oil pan gasket - these leak and it's almost guarantee at least one of them will leak. Will be good to know if some of them were replaced recently. Don't just take word for it - at least check receipts or invoices etc, if you don't know yet how to physically check them to see if they were indeed replaced recently or not. Worst one is oil pan gasket leak - it's most expensive to replace, then it's valve cover gasket. You will need to check under the hood after test drive to see if there are any leaks

For 335 specifically you will need to pay attention to additional things (on top of everything that was said above) like:
3. HPFP - it's a high pressure fuel pump (under the hood, not in tank - that one is low pressure one and fails less often). There was a free recall several years back - check to see if it was replaced or not.
4. Turbos - early models have high rate of failures due to a small part - bearing/rod in wastegate - it becomes loose and rattles not providing full tight closure. You will need to listen to engine sound when revving/accelerating. Go to youtube videos and listen how it sounds - it is really noticeable and means you are in $2-3k repair. The higher the mileage the more chances it will happen. So my advise is to look for e92 that had them replaced by warranty recently - so you'll be good for another 80-100k or so. Warranty was 8 years or 84k miles (i don't remember exact mileage number). So your e92 better have this replaced if you want to have a piece of mind buying it. So in your case 07-08 e92 has to had this replaced like 2-3 years ago - that's still better than buying a e92 with original turbos still working, but which may start failing anytime
5. Also for 335, and this is more maintenance wise - it will require more maintenance like changing coils/spark plugs more often than with 328 and doing walnut blasting - this is not issues in itself, but it will require more money from you to spent on maintenance.
Also, don't buy without taking it to a reputable shop for inspection - some Euro shop or the one that deals with german cars, if you drive it to some local Dodge average Joe shop - they can miss a lot of stuff

Now, my personal advise is to go for 335 - because I've been there and you will eventually want more power and it makes more sense to buy 335 in the first place, even if it's more problematic machine than 328. It's just 335 is a beast and if you have a chance to make a choice - think what you really want before you buy
