I've owned 12 bikes in 2016 and now have 3 .... I buy bikes, ride them a while, then sell for profit and buy better. (my first bike was a £40 Ridgeback Comet Hybrid... sold it for £120
) .... this keeps the wife happy as I don't use food money to buy bikes
my current summer commuter is a Specialized S-Works with Campagnolo wheels and full Campagnolo Chorus Groupset .... I paid £500 for it and it's by far my best bike. (I will keep this one for a long time, and will upgrade the wheels to Campagnolo Bullet soon) .... this one is fast and fits me like a glove
My supposidly 'fast' bike is a Giant TCR carbon, but even though I paid a bit more for this one, I still prefer the S-Works. I'm seriously thinking about selling the Giant later in the year and perhaps getting a Scott Foil with Di2 which I'm hoping will be a 'keeper'
I owned a 1980's
Condor (531 steel), and I really enjoyed riding this, but ended up selling it for a huge profit to someone in my village.... a lovely comfortable bike and I'm sad that I sold it
I owned a 1980's Koga Miyata Road Champ ... it was way too big for me and would love to get a Koga Miyata that fits .... I sold this one for 3 times what I paid
I owned a Surly Long Haul Trucker (bought it brand new for a bargain and sold it 2 weeks ago for £100 more than what I paid) .... I bought it with the intention to do Audax and LeJog, but it's just way too slow (I'd rather use a fast bike)
loads of other bikes (Carrera TDF, Bridgestone MTB, Gitane Tour De France (a very good bike IMHO) etc etc),
My latest bike (to sell on) is a 1980's Pinarello .... I'm hoping to double my money and get a 1980's Colnago or De Rosa which will be a 'keeper' and which will be my 'Sunday show off' bike and possibly ride a few L'Eroica events)
I'm also planning to get a vintage racing Tricycle such as a Bob Jackson or similar but that will have to wait until the 3rd quarter of this year
so.... the moral of the story is that it's not what you pay for the bike, it's how it fits you and how fast you can travel on it
