Yeah I wasn't being clear enough, sorry. I meant maintenance as more maintenance than a 2014 guitar. Like, if I'm buying a 1973 guitar, what should I check, etc. I've never bought vintage stuff hence my question. I'm talking about
this guitar(I can have it for less than the original price).
Well, it depends. Some models have changed dramatically over the years. The Tele's didn't, but the deluxe models are a different item from normal Teles. IIRC, the Tele Deluxe models had Humbuckers, but there you are looking at sound preference versus more 'maintenance'. Your primary differences between a '73 and modern is going to be styling (CBS era headstock), 3 bolt vs. 4 bolt neck plate (not sure if this matters, really), pickups (probably lower quality in that era compared to recent ones) and finish quality could go both ways depending on care and what modern models you're comparing it against. Wood handles itself, but obviously the older it is the more you have to be looking for obvious abuse and unexpected wear. Tuners won't hold as well as modern locking ones, obviously, but people have been using vintage for decades still and have no issue, YMMV. Bridges haven't changed (much), though you may elect to replace it or the saddles to set and keep intonation easier. I'm not sure if the '73 had already gotten away from the 'dual' saddles (3 per bridge) the original Teles had.
The way you'd
typicallyrun into more 'maintenance' issues, aside from parts that haven't been well preserved (IE, left in a moisture-rich environment, with an object laying on top warping the neck, etc.) are with the old bridges. A LOT of Fender models have really, really shitty saddles and/or bridges. Doesn't mean they don't work, but you will be monitoring your tuning a lot if you bend. Strats are obviously worse, but if you're used to modern tuners on a bridge with graphite saddles now it will feel like a huge leap backwards. Plus at some point you don't want to replace any of the 'vintage' stuff because of value and what not. I don't think a Tele is as much of a worry, add some nut lube or carefully replace the saddles with graphite ones (not exactly a huge part) and just keep the originals.
You may very well need to get frets leveled or replaced, however that's true with any used guitar it just depends how much you want to put up with. Hell, my 2011 Strat probably needs some fretwork done...
My 2c anyway.
