Is 105 still entry level?

[Veloo]

In '88 I got my first adult bike.
Columbus Matrix frame and fork.
Full 105 6 speed group.
Mavic MA2 rims.
Don't recall the cockpit.

$700 CAD.

According to Bank of Canada inflation calculator, $700 then is $1500 now.

Can you actually get a "basic" 105 bike for $1500 now?

My assumption back then was that 105 was entry level (affordable) road "racing" components. No interest in Exage or lower.

Haven't kept up with gruppos or pricing in many years.
Are Tiagra, Claris, Sora now the affordable road racing entry level stuff?
